Hi York Optical is in the city (Fortitude Valley).
Sirius Optics is in a suburb called Underwood 30 mins out of Bris city.
Star optics are at mermaid beach on the Gold Coast - they usually have a few scopes in the foyer of the Spacewalker.
Check them out via google.
I often check Sirius Optics website as they have a used equipment page.
